AUTOMATIC CABLE-.ATTACHER FOR SA'LVAGE-WORK.

Specification ofLetters Patent.

Patented Dec. 31,1918.

Application filed May 13, 1918. Serial N o. 234,311.

lTo all 'whom z'may concern:

Be it known that I," CoNsTANTnvn E. M. TAMBAcoPoLo, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Automatic Cable-Attachers for Salvage-Work, of which the following is a specication.

This invention relates to apparatus for raising sunken vessels. v

The invention is particularly adapted for use in salvage work and has for its primary object the provision of an apparatus which will consistl of means for eliminatin the use of divers inthe work of connecting t e apparatus with sunken vessels and treasures and for effecting an effective automatic application of a draft connection with the vessel or object to be raised so that the latter can be expeditiously drawn to the surface of l the water in any suitable well known manner.

*Y A practical embodiment ofthe invention is represented in the accompanying drawings forming a part of this specification and in which similar reference numerals 1nd1- cate corresponding parts in the several views and wherein Figure 1 is a face view of the a paratus. F Fig. 2 is a section taken on the me 2-2 of Fi 3 is a vertical section through the combmed drill and tap.

Fig. 4 is a section taken of Fig. 2, and

Fig.' 5 is a section taken on the line 5-5 v there `suitable for the .pu ose will bexemployed.

I- do wish to descri e, however, that they will possess the desired magnet power to 'enaJbl'e 'ven weights to be properly supported bly when in contact therewith.

Located within the frame or casing 10.is

I a hollow shaft 12 mounted in bearings 13 and 14 and o ening toward that side of the casing'` on w ich said magnets 11 are arranged. This hollow shaft is disposed 1n the on the line 1 4 same general line with a hollow sleeve 15I lfixedly connected with the casing at 16. The

surfaces are in contact with the dat wallsof the 'bore 17 so that when power is transmitted to the hollow shaft, it in turn will be directed to the member 19 to cause feeding movement thereof in the sleeve 15 and said hollow shaft 12. One end of the member 19 is attached to a draft cable 22 which is adapted to be extended to a hoisting apparatus upon ay iioating vessel from whichthe work of hoisting is to be conducted. The opposite end of the member terminates ina tap 30 having a drill 23 which passes through a movable washer 24.- on the casing 10.

A motor or suitable well known power plant 25 is arranged in the Vcasing 10 and the drivin shaft thereof is provided with a gear whee 27 and the latter is disposed to'coact with a power multiplying gear t'rain 28 including a fixed gear wheel 29 -lixed to the hollow shaft 12.

From the described construction ,of the.

apparatus, it will'be observed that the magnets 11 serve to maintain a fixed relation of the drill 23 to the hull of the vessel to be raised and that after such connection .is established, ower is imparted to the drill to advance t e same against its work. In

this manner, a passage will be formed in the hull of the vessel and successive with the formation of said passage the tap 30 will follow the course taken bythe drill to thread the walls of said passage for its -subsequent receipt of the bolt 20. A firm connection is tioned draft connection, the vessel can be raised to the surface of the Water in an ex- `now produced between the vessel to lbe raised Y and the apparatus and by means of the meneditions manner. Other hanging cables can e employed and connected wlth eye mem,-

bers 31 on the casing 10. When the headed portion 21 of the screw 20 reaches the Washer 24, the latter is detached and applied against the walls of the hull of the vessel with said squared head of the bolt in firm engagement therewith.

'What is claimed as new is 1. A salvage machine comprising a bolt having a squared head, an interiorly threaded member, an exteriorly threaded extension on the bolt at one side of the head thereof arranged in said interiorly threaded member, a draft cable fixedly connected With said extension, means revolving against the head of the bolt and operating to accommodate the same for longitudinal adjustment, mechanism for revolving said means to feed the extension through said member, a tap located in advance of the bolt and forming a fixed part thereof and a drill forming a fixed part of the tap and arranged in advance thereof.

2. A salvage machine comprising a bolt having a squared head, an interiorly threaded member, an exteriorly threaded extension on the bolt at one side of the head thereof arranged in said interiorly threaded member, a draft cable ixedly connected with said extension, means revolving against thehead of the bolt and operating to,V accommodate the same for longitudinal adjustment, mechanism for revolving said means to feed the extension through said member, a tap located in advance ofthe bolt and forming a fixed part thereof, a drill forming a fixed part of the tap and arranged in advance thereof, means for holding the drill end of the bolt against its Work, anda removably supported Washer apertured for the free movement of the drill and said tap therethrough and adapted to be projected against the work under the action of the head of the bolt. 3E 3. A salvage machine comprising a frame, an internally threaded member fixed to the frame, revolving means having one end journaled in the frame, said means having a continuous squared bore, mechanism for e0' revolving the means, Aa bolt slidable in the bore of said means and provided With a squared head freely engageable With the Walls of said bore, a threaded extension formed onthe bolt Aand operating in said member, a cable fixed to the extension, a Washer removably supported from the frame in line With the bore of said means, means for holding the frame against its Work, a tap carried by the bolt, and a drill extending from the tap and freely movable through the Washer, the Washer disposed in the path of movement of the boltfto be engaged by the head thereof, as and for the purpose specified.

In ,testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses, this 29 day of April .1918. p
